Some carefully crafted libraries make promises to their
users beyond functionality and performance.
Examples are: Fusion libraries promise intermediate data
structures to be eliminated. Generic programming libraries promise
that the generic implementation is identical to the
hand-written one. Some libraries may promise allocation-free
or branch-free code.
Conventionally, the modus operandi in all these cases is
that the library author manually inspects the (intermediate or
final) code produced by the compiler. This is not only
tedious, but makes it very likely that some change, either
in the library itself or the surrounding eco-system,
breaks the library's promised without anyone noticing.
This package provides a disciplined way of specifying such
properties, and have them checked by the compiler. This way,
this checking can be part of the ususal development cycle
and regressions caught early.
See the documentation in "Test.Inspection" or the project
webpage for more examples and more information.
